Filed: 1994-03-17
Abstract: PURPOSE: To raise the pH of ordinary drinking water by adding a small amt. of a concd. alkaline auxiliary soln. contg. potassium hydroxide and sodium hydroxide to the water.  
     CONSTITUTION: An alkaline additive soln. is diluted with 9 times as much distilled water as the soln. The additive is formed by combining potassium hydroxide with sodium hydroxide in a range of about 95% potassium hydroxide and about 5% sodium hydroxide to about 50% potassium hydroxide and about 50% sodium hydroxide. A one ounce bottle with a droplet cap is used in order to conveniently add the additive into ordinary glass of drinking water in order to readily form an alkaline drinking water. About 600-800 droplets are contained in a one ounce bottle of the additive. When two droplets of the additive are added into ordinary tap water in a ten ounce glass, the pH of the water increases from about 7 or 8 to about 10-10.5. This pH change means about 50 mg potassium and 9.8 mg sodium per one water filled glass.

Abstract: PURPOSE:To prevent a crack in resin sealing package surely. CONSTITUTION:Each embossed part 21 is formed on four corners of a tab 18 in a TQFP-type IC 29, while each top of embossed parts 21 is exposed from the rear face of a package 27. A small hole 22 for joining from inside to outside is formed in the embossed part 21 and then, the embossed part 21 has an effect like an anchor against flaking force produced in the resin sealing package 27. Then, in a heating step for the IC 29, flaking is hardly caused at an interface between the tab 18 and the resin even when there is a difference in thermal expansion coefficients of these materials. Consequently, a crack from flaking is prevented, and when steam explosion takes place through moisture absorption by the resin sealing package 27, the explosive force is dispersed outward through the small hole 22 in the embossed part 21 to an exposed part under the package 27, and a crack caused by steam explosion can be prevented.

Filed: 1979-04-20
Abstract: PURPOSE:To obtain a simplified current dividing circuit by providing plural emitters and collectors, where effective emitter and collector areas are set in respective division ratios, and a base biased commonly. CONSTITUTION:The effective emitter area ratio of P-type semiconductor regions 1a and 1b which constitute the injector of an I<2>L circuit is set to, for example, 1:2, and effective collector areas of P-type semiconductor regions 2a1-2a3 and 2b1-2b4 which constitute collectors corresponding to them are divided into three and four equally respectively. N<-> type semiconductor region 3 constitutes a practical base region and is biased to the earth potential. If emitter regions 1a and 1b are made common and constant current I0 is flowed, the current input from injector 1a to collectors 2a1-2a3 becomes I0/3X1/3=10/9. Meanwhile, the current input from injector 1b to collectors 2b1-2b4 becomes 2I0/3X1/4=I0/6. Consequently, different constant current loads can be obtained from one constant current source by a simplified circuit.
